Eurocompulsion Performance Intakes Official Thread

I want to start by explaining our design principles. We are big believers in using the highest pressure coldest air possible while minimizing the chances of foreign object ingestion. In most cases that means that the factory's fresh air duct is the best place to draw air. We utilize the highest quality silicone in several layers with reinforcement weave between the layers. This does several things for us. First, it looks great, and stays looking great. It doesn't tarnish, rust, or deteriorate in any noticeable way, it essentially lasts forever. Silicone also provides very effective insulation against engine compartment heat. This helps keep the air cool.
Here is a picture of the overall air routing in all of our 124 intakes:

The factory fresh air duct is located in such a way that it receives high pressure cold air, but minimal dirt and debris. It does this by using the inertial separation principle. That simply means that it requires air to make a turn before entering the duct. Anything that's not really small can't make that turn so the bigger pieces of sand etc. stay out of the intake. All of our intakes retain these features.

Let's look at our first Intake, the V1. The V1 retains the stock air filter box, but replaces the main intake air tube with a higher quality piece that's more free flowing. In testing we were shocked how badly the stock piece flowed, that correlated flex section of the stock piece really disrupts airflow. We smoothed out the design using a single humper for flex, and used thick silicone to keep the air cool.
The V1 intake gives a small increase in power and has no increased noise level over stock, except possibly very slightly at full throttle (I can't hear any difference, but my son says he can). Since it's a direct replacement part it looks essentially like a stock intake if ordered in black, which is important to some people. It's a great intake and can be used with either the stock air filter or a K&N filter. The power gains with both filters are identical.

Our next intake is the V2. This one is a little bit more of an enthusiast's intake. It's definitely noisy, you will hear the turbo whistle, the diverter valve release air, and other noises from the intake system. It's not too loud, but you will hear it in any spirited driving situation. The tubing is the same high quality multi-layered silicone used in our other intakes. It uses an open element filter which is very free flowing, yet filters well. The filter is located in the coolest spot in the engine bay right by the fresh air supply duct.
The V2 offers slightly higher performance than the V1 in most, but not all conditions. Since it's not sealed to the fresh air duct, it requires forward movement for a supply of cool air. So it's possible at low speeds or in traffic for it to heat soak a little, in which case it's performance will be about equal to the V1. It's a great intake, and is likely as good as it's possible for an open element filter intake to be without exposing the filter to hydrolock or other problems.

Our third new intake is the V4. This our best intake for the 124 by almost any measurable standard. It's a true Ram-Air intake meaning that the faster you go, the greater the pressure in the intake system. It maintains higher intake pressures than any other intake even without the car moving and it's advantage increases with speed. It also has the lowest temperatures. This intake makes the most horsepower in all conditions and should be the intake of choice for hotter tunes like our "Race" tune.
It's a little louder than the V1, but not as loud as the V2. In normal driving you will NOT hear it, but it gives a quiet roar at full throttle. The filter canister is a real carbon fiber unit, that's not a sticker, it's the real deal. It filters well and flows well. The filter is washable so it can be reused almost indefinitely. It's more expensive than the other intakes, but it's better, and if you want maximum performance or plan serious mods with 25 pounds of boost or more, this is the one you want.

Now for the data!
We pride ourselves on our testing. We test all our designs on a flow bench and of course on the real car. We measure just about every parameter and optimized the design. In the case of the 124 we found that the location of the evap port on the silicone tube was critical for preventing the dreaded P1CEA check engine light. We took the time to get this right. With our intake you will NOT get a check engine light.
In the next pictures you can see the pressure data from the flow bench. It's pretty self explanatory, all our intakes easily out flow the stock intake. The temperature data is taken after the intecooler with the car at full boost in second gear, so it had enough forward motion to keep things cool. Remember that with the V2 there are conditions where the temperature can be higher than stock, but as long as the car is moving it does pretty well.

Power results. All our intakes give you more power, the gains from the V1 are mild, but in my opinion worthwhile for those who want to retain stock noise levels and near stock appearance. The V2 gives more, and the V4 is the leader in power.

Pricing:
The V1 is 168.99 and can be found here: https://shopeurocompulsion.net/coll...ider-v1-air-induction-kit?variant=26725372609 Note: you can add a K&N filter at extra charge. However in extensive testing we found it offered no performance advantage. Frankly we were surprised by this because usually they do. However the K&N did not outflow the stock filter on the flow bench. An inspection revealed the reason. The stock filter has pleats about twice as deep, thus the K&N filter has about 1/2 the filter area However it does flow equally well, due to it's superior materials, and it's washable and reusable, so it's still a good product.
The V2 can be found here: https://shopeurocompulsion.net/coll...mpulsion-fiat-124-spider-v2-air-induction-kit This particular style of intake is typically very popular because it performs well, sounds aggressive, and looks good.
The V4 is here: https://shopeurocompulsion.net/coll...n-fiat-124-spider-abarth-v4-air-induction-kit . This is the one I am running on my car. It's expensive, but it's the best.

You have put a great deal of engineering and thought into these intakes. As far as cost even the V4 is well within reason for what you are getting. In my 45 years of modifying every imaginable kind of vehicle I have spent a lot more money for a lot less intake. Looks great and has been added to my list of items to get. When will they begin shipping?
They are ready to ship now. However we only have about 5 of each as we don't have a feel yet for what intake or color will sell the best.

Greg,
The Hp /Torque numbers you show for the air box mods are on a stock engine correct? Also are the euro+drive lite HP/Torque numbers with a stock car...no modified exhaust or airbox? Do you have numbers of the euro+drive lite with the V4 air box? Correct any of the above statements if I am incorrect and thanks for all the information.

Hi Clay,
All the power numbers are on a stock engine. That means STOCK, no exhaust mods, no Euro+Drive Lite. The V1 results are with the stock filter. The Euro+Drive Lite results are with the stock intake system, no other mods. All of the intake numbers we measured on the same day within a two hour period so conditions stayed constant. Same with the Euro+Drive Lite numbers.
At this time we do not have combined results. In other words we don't have Euro+Drive Lite combined with intake numbers. I prefer to keep these things separate.

That is what I thought...numbers for the euro-dive lite with the V4 air box could be even more impressive.
Throw in a muffler delete and they may be even better. Thanks.EDL with a V4 and improved exhaust should be awesome. However to avoid confusion we are posting power numbers for individual modifications. On my personal car, I plan to run the EDL "Race" tune and a red V4. We did that in testing and it was very strong, especially at the high end.
In testing we ran the V2 intake with the EDL "Dynamic" tune quite a bit. That's a pretty fun combo too.

See this is the stuff I like to see. Some real quality materials and products. With real data to support why the heck we should buy it. Not some bull-nonsense values thrown at a chart with a heck of a ton of discrepancies and terms and conditions ! Sweeeeet !
